RAILWAY-CAR COUPLING.

SPECIFICATION forming part of Letters Patent No. 621,978, dated March28, 1899.

Application filed J'uly 26,1898. Serial No. 686,925. (No model.)

T0 all wwn it may concern:

Be it known that we, FRIEDRICH SCHEL- LINGER and FERDINAND KLEINER,subjects of the Grand Duke of Baden, residing in Ahausen, in the GrandDukedom of Baden, Germany, have made certain new and useful Improvementsin Railway-Car Couplings, of which the following is a specification.

Our invention relates to a car-coupling which will permit two cars beinguncoupled while running and which is distinguished in that all thecouplings of a train may be connected one with another in order to beoperated simultaneously,while, on the other hand, this connection Inaybe interrupted at any point in a most simple and convenient manner.

That the invention may be fully understood reference will be had to theannexed specification and the accompanying drawings, in which- Figure lrepresents a side elevation of the ends of three railway-cars providedwith the new coupling. Fig. 2 illustrates a plan view of the coupling,and Figs. 3 and 4 show detail views of the coupling.

Similar letters of reference indicate corresponding parts in thedifferent iigures.

rlhe essential features of the coupling consist in a frame-like shacklea, Fig. 4, and the tongs A, being attached to the ends of the cars. Thesaid tongs A consist of a rigidlymounted leg c, Fig. 3, forming anextension of the usual coupling-rod c', and of an arm b, being pivotedto and leaning against the latter from below. The free end h' of thesaid arm b is continuously pressed downward by means of a powerfulspring s,- so that the tongs will be always locked. The arm b isprovided with a recess b2, into which the end of the said shackle ct isneatly fitted and by which it is firmly held in position when the arm bis leaning against the leg c. When two cars are brought together, theshackle a,which has been fixed into the tongs of the one car and is heldhorizontally by the sam e, automatically engages the tongs of the othercar, so that an automatic coupling takes place.

In order to prevent the coupling parts from being jammed together tooviolently, springs a', Figs. l and 2, may be fitted into the slit of theshackle a, which the legs of the tongs must press apart when the carsmeet, thus easing the shock.

The opening of the tongs-that is to say, the uncoupling of the cars-iseffected by means of the operating-lever e or by hand-wheels or thelike, which may be arranged on both sides of the cars by means of atransverse shaft d. The said shaft d carries an eccentric disk j', whichsupports the free end b' of the lower part or arm b of the tongs andlifts the arm b' when the shaft c is turned, thus keeping the arm b offthe leg c. On the shaft d is also provided an arm g, being connected bymeans of a link h with a double-armed lever t', pivoted'to the car end.The link h transmits motion from the shaft CZ to the lever 1I. Thelevers t of the corresponding ends of the cars may be connected at theirupper ends by means of draw ropes, chains, or the like'c 7c' 71:2, Fig.l. If I is supposed to be the front car Vand I I the next following carand the coupling of the front car I is opened by means of its hand-levers, motion will be transmitted from the lever t' of this car to the levert' of the next following car I I by the rope 7s and to the nextfollowing car by means of the rope 7a2, dac. Therefore with the frontcar all the other cars may be simultaneously and automaticallyuncoupled. If, however, the ropes 7c k2 are not attached to the leverst', the coupling of the carl only will be uncoupled by lever c of thecar I, while the other cars remain connected to the latter. In the likemanner the levers t', situated at the opposite ends of the cars, may beconnected by means of draw-ropes. The operating of the coupling can beeffected instead of by the levers e, situated at the side of the cars,by directly operating the levers t', for instance,'from a brakemans box.

For the purpose of attaching or detaching the ropes k Zo' k2,respectively, to or kfrom the levers c' the following arrangement may beused: The ropes k 7c are provided at their ends with rings r, by meansof which they are hung over fingers t', attached to the upper ends ofthe levers t'. The lever t' has a guide 2, in which a bolt Z is sliding,which may be moved up and down bya bell-crank lever m,

pivoted to the lever i, or by any suitable means. lf it is intended torelease the ropes 7,; 7c' from the levers z', in order not to transmitmovement to the coupling ofthe following ears, the bolt l is movedupwardly by moving the bell-crank lever m in the direction of thearrowinto the position shown in dotted lines on the car I, Fig. l, or bythe other means used, so that the rings o" are shifted oit the lingersi', and thereby the ropes released from the levers yi.

lVhat we claim as our invention, and desire to secure by Letters Patent,is*

l* In a ear-Coupling the combination of a link a with tongs A attachedto the ends of the ears, the said tongs consisting of a rigidlymountedleg c forming an extension of the coupling-rod c', and of a recessed arml) pivotcd to and leaning against the latter from below, the free end l1of the said arm I) being continuously pressed downward by means of aspring s, an operating lever or levers c arranged on one or both sidesof the ear upon a transverse shaft d, an eccentric diskfon said shaft,and an arm g on this shaft, the latter being connected by means ol alink h with a double-armed lever t' pivoted to the car end,substantially as described.

2. In a car-coupling means for attaching or detaching the draw ropes orchains respectively to or from the double-armed levers t', consisting ofrings r attached to the ends of the ropes or chains, by means of whichthe ropes or chains are hung over fingers z" of the levers z', thelatter bein g provided with a guide i2 and a bolt Z sliding in the saidguide and when moved upwardly releases the rings r from the fingers'11', substantially as described.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
